      Sometimes, my agent goes offline on my Windows 7 virtual machine. It stops executing the current script and give me this code :

      Agent went offline during the build
ERROR: Connection was broken: java.io.EOFException

      What is strange is that if I open my virtual machine , and watch it, I won't get this error. Somehow, it happens only when I let jenkins start the VM by itself
      I've put all the plugins and jenkins' version, because I really do not know where this comes from.

          happens too often, especially with long running tests on slave VMs;
          maybe the timeout should be increased or re-connecting tried for a while.

          I have this issue as well, only difference is that it does not matter for me if i start the VM and i watch it or if jenkins starts it, it will give that error near the ending of the build, after an hour.
          I managed to trigger the error as well if i open the VM, watch it and give it the restart command, it will register this same error.

          Constantly having this issue, on my Ubuntu node. Is this issue fixed? Also, is it prevalent on Jenkins nodes?
